当TZ=":/etc/localtime“时，获取本地时间的正确方法是什么？

#include <stdio.h>
#include <time.h>

int main() {
    time_t now = time(NULL);
    struct tm *local_time = localtime(&now);
    
    int year = local_time->tm_year + 1900;
    int month = local_time->tm_mon + 1;
    int day = local_time->tm_mday;
    int hour = local_time->tm_hour;
    int minute = local_time->tm_min;
    int second = local_time->tm_sec;
    
    printf("当前本地时间：%d年%d月%d日 %02d:%02d:%02d\n", year, month, day, hour, minute, second);
    
    return 0;
}
